43AP Pneumatic Indicating Controllers
These instruments indicate and control pressure, temperature,
vacuum, and differential pressure. They provide process industries
with a highly dependable and versatile group of instruments.
WIDE SELECTION OF MEASURING ELEMENTSInvensys Foxboro offers the
widest variety of element constructions and ranges in the industry.
This versatility enables the 43AP Series Pneumatic Indicating
Controllers to be applied to virtually any process.
WIDE CHOICE OF CONTROL MODESOn-off, proportional, proportional
plus derivative, proportional plus integral (reset), proportional
plus integral plus derivative, differential gap, and automatic
shutdown actions are available.
BROAD RANGE OF INTEGRAL (RESET) AND DERIVATIVE ADJUSTMENTSThe
integral unit has the complete range from 0.01 to 50 minutes, and
the derivative unit from 0.05 to 50 minutes.
VARIETY OF OPTIONSThese controllers are available with an
extensive list of optional features. Among these are internal
bumpless automatic-manual transfer stations (two types), “batch”
function, remote pneumatic set point, Type 70 electric contacts,
and control valve mounting.
ACCURACY UNAFFECTED BY MOUNTING STRESSESBoth the control unit
and the measurement element are mounted on a rigid steel plate.
Thus, these components are isolated from case stresses due to
mounting, and dependable accuracy is ensured.

PSS 3-1B3 APage 2
POWER FAILURES DO NOT INFLUENCE PROCESS-DRIVEN INDICATIONA power
failure and the likely subsequent loss of supply pressure do not
influence the process-driven indication.
WEATHERPROOF CONSTRUCTIONA glass fiber reinforced case and a
gasketed door with a shatterproof polycarbonate window meet IEC
IP53 and provide the environmental protection of NEMA® Type 3.
VERSATILE MOUNTINGInstruments may be mounted in a panel, on a
flat surface, on a continuous vertical pipe, or on a vertical pipe
stub.
INTERNAL BUMPLESS AUTOMATIC-MANUAL TRANSFER STATIONThis option
provides bumpless-balanceable transfer between automatic and manual
control by simple 2-step procedure. Accidental transfer is avoided
because the door must be opened to gain access to the transfer
station.

Optional Feature DescriptionAS (a)
Reference
BumplessAutomatic-
Manual Transfer Station
Consists of precision balance tube, regulator, and 2-position
switch located within enclosure. A simple 2-step procedure provides
bumpless transfer between automatic and manual control. A shutoff
valve is supplied to allow automatic controller and relay to be
serviced while retaining manual control.
See Model Code
ozzle Seal Switch for Manual Control
An internally mounted 2-position switch provides a simple and
inexpensive method of achieving manual control. In the manual
position, the switch seals the nozzle circuit and the output can be
changed by varying the controller supply pressure with an external
regulator.
See Model Code
Remote Pneumatic Set Point
Integral Air Supply Set
Enables the set point to be positioned from a remote source
using a standard pneumatic signal. Available over the full span or
part of the span.
Fixed or adjustable combination pressure regulator and filter
with 50 mm (2 in) gauge mounted and piped to controllers. Fixed
pressure regulator available without gauge. Maximum input 1 MPa,
150 psi, or 10 bar or kg/cm2. NOTE: Not available with panel
mounted controllers.
See Model Code
IAS
ype 70 Electric Alarm Contacts
This option comprises a rotor unit with up to 5 contacts. Relays

point adjustment mechanism. ESP
High “Batch”Modification
For processes involving discontinuous control, the integral
(reset) function is modified to prevent overshoot and to initiate
immediate corrective action when control is resumed.
BATCH-H
Gas Tight Case Special case machining and a gasketed 1/2 NPT
vent connection permits operation of the controller with clean,
noncorrosive process gas.

Manual Switching
For use only with controllers not having internal transfer
switching. Consists of pressure regulator, nominal 40 mm (1.5 in)
gauge, and 2-position transfer switch completely piped and
assembled to external subpanel mounted to bottom surface of
enclosure. Subpanel is finished in gray. The 1 in AS Code is for
Control Codes A1, A2, A3, A7, and A8. The 2 in AS Code is for
Control Codes A4 and A5. The S in AS Code is gauge in kPa, the E is
